Get some advice from a lawyer in your area. AS IS so to speak is different everywhere. If they gave you an inspection report, as a recognized dealer, being that equipment and the condition of equipment is there area of expertise, a reasonable person may take that to mean they are standing behind the piece of gear to some degree. Its all in the wording I suppose . As well, if they gave you the inspection as a sales tool, that may carry some weight. As opposed to giving you the inspection after you write them a cheque. I have had some minor dealings in this area, not overly comparable, but the advice is to seek professional advice. Incidently, stay away from giving to much information when staging your complaints folks. Instead of saying; " i bought this used machine and only used it for 4 hours to push snow" stick with "I bought this machine and look at the huge crack in the arm". Let them figure out that you used it 4 hours and ask what those 4 hours were for. And of course the answer would be " 4 hours digging feathers". Not being critical of Muddy's approach, most people assume that buying from a dealer provides you with some security of purchase as opposed to just buying from an auction for cheaper. Hope they come around in the end.
